Review on 3M 07521 Multi Flex Abrasive Sheet by Paul Ward

This abrasive sheet does an excellent job of finishing, sanding, and smoothing surfaces. Its flexibility allows it to reach hard-to-reach areas that other sanding sheets can't.It is perfect for INDUSTRIAL and scientific applications. The sheet is long-lasting and can be used on almost any surface. The only downside is that it might be a bit too abrasive for delicate surfaces..
